CHARLES A. SARGERT, OF ROCHESTER, PENNSYLVANIA.

APPARATUS FOR INSERTING OR WITHDRAWING'CASING FOR OIL OR LIKE WELLS.

SPEGIFIGATION forming part of Letters Patent No. 484,051, dated October11, 1892.

Application filed May 18 1892.

To aZZ whom it may concern.-

. Be it known that I, CHARLES A. SARGERT, a resident of Rochester, inthe county of Beaver and State of Pennsylvania, have invented a new anduseful Improvement in Apparatus for Inserting or Withdrawing Casing forOil or Like Wells; and I do hereby declare the following to be a full,clear, and exact description thereof.

My invention relates to apparatus for inserting casing in oil or likewells and for withdrawing the same, its object being to provide a formof apparatus which will greatly reduce the time and labor heretoforenecessarily expended in the performance of this operation.

To'enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich- Figure 1 is a plan view of myimproved device. Fig. 2 isa verticalside view. Fig. 3 is a plan view with the top ring removed. Fig. 4; isan enlarged detail view in section of the manner of guiding therevoluble ring and the manner of supporting the same.

Like letters of reference indicate like parts in each.

The frame A is composed of the standards or struts a,bolted to thefloorb of the derrick, said standards or struts supporting thestationary ring 0. For purposes which will be fully hereinafterdisclosed, the circumference of the ring a is provided with the tiltingor canting section 0', which is composed of the segments cl d, boltedtogether by the bolts 61 To provide for the tilting or canting of thesection 0 the said section is connected to the circumference of the ring0 by the swiveljoint 6. (Shown in dotted lines in Figs. 2 and 3.) Thesection 0' is provided with the journal-box f. Secured to the stationaryring 0 are the brackets g, carrying the idle rollers or pulleys g, saidrollers or pulleys having the annular grooves g formed therein. Therevoluble ring h is supported above the stationary ring 0, saidrevoluble ring it having the projecting edge or flange h adapted to fitwithin the annular grooves g of the idle-rollers g, said rollersassisting to support the said ring h and acting as guides to preventsaid ring from wabbling during its rotation.

The lower face of the ring it is provided with Serial to. 433,413. (NomodeL) the teeth 2', with which the gear-wheel j is shaft beingjournaled in the journal-box f.

The opposite end of the shaft k is journaled in suitable bearingsin thestandard Z. Mounted on the shaft is is the gear-wheel m, adapted to meshwith the gear-wheel n on the counter-shaft n, journaled in the standardZ. sprocket-wheel 0 is secured to the countershaft n, a driving-chain 19passing therefrom to a suitable power-driven shaft, such as that onwhich the bull-wheel is mounted. Bolted or otherwise secured to the rimof the revoluble ring his the upright arm g, which is preferablyprovided with the outwardly-projecting extension q, said extension beingpivoted to the arm 1" by the bolt or pin The opposite end of the arm ispivoted to the link 8 by the bolt or pin r. The link 8 is formed withthe hook s, which is adapted to engage with. the lever 25. The lever 23is provided with a bifurcated end 25', adapted to embrace the casing 10and be secured thereto in such manner that when the revoluble circle his revolved the casing u will likewise revolve to screw it into place.This construction provides a connection between the revoluble ring itand the casing u, which has a certain amount of play at each joint. Byhaving the arm (1 formed with the out wardly -projecting extension q agreater amount of leverage is obtained when the ring it is revolved toturn the casing 4.0. Any other suitable form of connection between thering it and the casing u may, however, be employed.

The operation of my improved apparatus is as follows: When it is desiredto .inserta section of casing or tubing, the said casing is supported bythe swivel connection '12, secured to the cable or rope to, which passesup over a suitable pulley at the top of the derrick. The casing islowered by means of the cable to to bring the lower end thereof intoposi tion to engage the threads of the last piece inserted. The lever tis then secured to the casing to, when power is applied to rotate theshaft 70. This will drive the gear-wheel j, and through it the ring h.As the ring h to tates and as the lever t is secured to the casing u,the result is that the casing u is likewise rotated, so that its end isscrewed into the upper end of the section of easing last inserted. Theswivel 2) permits the turning of the casing 11. without the twisting ofthe cable w. In this manner the casing may be quickly inserted andscrewed into the preceding section. The apparatus may be set up andoperated by two men, whereas in the ordinary manner of inserting casingit re quired from four to six men. At the same time it insuresa betterconnection between the sections of easing, as by applying the power inthe manner described the sections may be screwed up tighter, so reducingthe liability of the casing separating at its joints when it is desiredto raise the same. The swivel -joint 6 provides for the tilting orcanting of the shaft 70 in case the floor of the derrick should sag toone side or the other, thus enabling said shaft is to maintain itsposition parallel with said floor. This sagging of the derrick floor isliable to occur, as the weight of the casing already inserted is carriedby the floor for a certain length of time after the insertion of eachsection of easing. In this manner the shaft 70 is relieved of anystrainwhich otherwise might be thrown upon it by any change in thefioor. The rotation of the ring h may be reversed when it is desired tounscrew the sections of tubing by changing the sprocket-wheel 0 from thecounter-shaft n to the main shaft It, or it may be reversed by clutchmechanism, as may be desired.

What] claim as my invention, and desire to secure by Letters Patent, is-

1. In apparatus for inserting or withdrawing casing for oil or likewells, the combination, with the frame, of a tilting or canting section,a power-shaft journaled in said tilting or canting section, andconnections between said power-shaft and a revoluble ring, andconnections carried by said ring to connect said ring to the casing,substantially as and for the purposes set forth.

2. In apparatus for inserting or withdraw ing casing for oil or likewells, the combination, with the frame, of a tilting or canting sectioncarried thereby, a power-shaft journaled in said tilting or cantingsection, a gear-wheel on said shaft adapted to engage with teeth formedon a ring supported by said frame, and connections carried by said ringto connect said ring to the casing, substantially as and for thepurposes set forth.

3. In apparatus for inserting or withdrawing casing for oil or likewells, the combination, with the frame, of the revoluble ring h, theupright arm q, provided with the outwardly-projecting extension q, thearm 1", the link 8, provided with the hook s, and the lever 25, adaptedto engage with the casing, substantially as and for the purposes setforth.

4:. In apparatus for inserting or withdrawing casing for oil or likewells, the combination of the stationary ring 0, the idle-rollers o, therevoluble ring h, supported by said rollers and carrying connections toconnect said ring it to the casing, the tilting or cantin section 0' insaid stationar rin 0 the journal-box f, the driving-shaft k, and thegear-wheel j, adapted to engage with the toothed face 7; on saidrevoluble ring h, substantially as and for the purposes set forth. Intestimony whereof I, the said CHARLES A. SARGERT, have hereunto set myhand.
